Imam Khomeini repeatedly through his historic speeches and messages pointed out the danger of Israeli occupation and expansionism.
Imam also warned about the fact that Israel would not be satisfied with its present boundary, and he informed the people that any kind of denial or cover-up by Israel of this aim was merely done to deceive public opinion in the Islamic world and allow it to pursue its step-by-step policy to achieve its ultimate aim.
Imam knew this and realized that the main buttress of the struggle would be the people's Islamic faith.
Imam Khomeini, the late founder of the Islamic Republic considered other methods of struggle, such as reliance on Arab nationalism and nationalist views along with other imported and non-Islamic ideologies, as a departure from the path of struggle for the freedom of Quds.
If this warning of Imam's alone had been understood properly, the way for the various conciliatory plans - which naively sought to make Israel the captive of international agreements and resolutions and, at the cost of giving it most of the occupied lands, obtain a kind of limited self rule in a corner of Palestine - would have been blocked.
Consequently, Imam Khomeini used to stress the importance of public knowledge and awareness in the Islamic world stemming from the principles of belief and the ummah's common faith and culture, and of avoiding sectarian differences.
